Unugyada qorraxdu waa aaladaha semiconductor kuwaas oo si toos ah u beddelaya shucaaca qorraxda tamarta korantada ee ku saleysan saameynta sawir-qaadista ee semiconductors.Unugyada cadceedda ee hadda la ganacsiyeeyay waxaa ka mid ah noocyada soo socda: unugyada cadceedda monocrystalline silicon, unugyada qoraxda ee polycrystalline, unugyada cadceedda ee silikoon amorphous, unugyada cadmium telluride ee hadda, unugyada selenide copper indium, unugyada dareenka nano-titanium oxide, polycrystalline silicon dhuuban unugyada qoraxda iyo unugyada cadceedda organic, iwm. Crystalline Silicon (monocrystalline, polycrystalline) Unugyada qoraxda waxay u baahan yihiin silikoon saafi ah alaabta ceeriin, guud ahaan u baahan daahirnimo ugu yaraan %, taas oo ah, ugu badnaan 2 atamka wasakh ah ayaa loo ogol yahay in ay jiraan 10 milyan oo silikon. atamka.Maaddada silikoonku waxay ka samaysan tahay silikoon dioxide (SiO2, oo sidoo kale loo yaqaan ciid) sida walxo ceeriin ah, taas oo la dhalaali karo lagana saari karo wasakhda si loo helo silikoon aan dhab ahayn.Laga soo bilaabo Silicon dioxide ilaa unugyada cadceedda, waxay ku lug leedahay habab badan oo wax soo saar iyo geeddi-socod, kuwaas oo guud ahaan qiyaas ahaan loo kala qaybiyay: Silicon dioxide -> Silicon-fasalka Birta->Trichlorosilane-nadiifinta sare -> polysilicon-nadiifinta sare -> monocrystalline silicon usha ama Silicon Polycrystalline ingot 1> wafer silikoon 1> unugyada cadceedda.
Unugyada qorraxda ee monocrystalline waxay inta badan ka samaysan yihiin silikoon monocrystalline.Marka la barbardhigo noocyada kale ee unugyada qorraxda, unugyada silikoon monocrystalline waxay leeyihiin waxtarka beddelka ugu sarreeya.Maalmihii hore, monocrystalline silicon solar cell ayaa qabsaday inta badan saamiga suuqa, ka dib 1998, waxay dib ugu noqdeen silikoon polycrystalline waxayna qaateen kaalinta labaad ee saamiga suuqa.Sababtoo ah yaraanta alaabta ceeriin ee polysilicon sanadihii la soo dhaafay, ka dib 2004, saamiga suuqa ee silikon monocrystalline ayaa kor u kacay wax yar, iyo hadda inta badan baytariyada lagu arkay suuqa waa silicon monocrystalline.Kaamirada silikoon ee monocrystalline silikoon unugyada qoraxda waa mid aad u fiican, muuqaalkeeda, korantada iyo qalabka farsamada ayaa aad u lebbisan.Midabka unugyadu inta badan waa madow ama madow, taas oo si gaar ah ugu habboon in la gooyo qaybo yaryar si loo sameeyo alaab yar oo macaamiisha ah.Waxtarka Beddelka ee lagu gaadhay Shaybaadhka Monocrystalline Silicon Cells
Waa %Waxtarka beddelka ganacsiga caadiga ah waa 10%-18%.Sababtoo ah habka wax soo saarka ee monocrystalline silicon solar cell, guud ahaan semi-dhammeeyay silikoon ingots silikoon waa cylindrical, ka dibna dhex mara jeexjeex -> nadiifinta -> kala firdhinta isgoyska -> ka saarida ee electrode gadaasha-> samaynta electrodes -> daxaliyay agagaarka- > dhimista uumiga.Filimka milicsiga ah iyo kuwa kale ee warshadaha warshadaha ayaa laga sameeyaa alaab la dhammeeyey.Guud ahaan, afarta gees ee monocrystalline silicon solar cell waa wareegsan yihiin.Dhumucda monocrystalline silikoon unugyada qoraxda guud ahaan waa 200uM-350uM.Isbeddelka wax-soo-saarka hadda waa inuu u horumaro dhinaca aadka u khafiifsan oo waxtarka sare leh.Soosaarayaasha unugyada cadceedda ee Jarmalka ayaa xaqiijiyay in 40uM silikoon monocrystalline qaro weyn uu gaari karo 20% hufnaanta beddelka.In wax soo saarka ee polycrystalline silicon solar cell, silikoon-nadiifinta sare sida alaabta ceeriin aan lagu nadiifin hal crystals, laakiin waa la dhalaalay oo lagu tuuray ingots silicon square, ka dibna baaraandegi galay xaleef khafiif ah iyo processing la mid ah sida silikon crystal hal.Silicon polycrystalline waa sahlan tahay in laga garto dusha sare.Waferka silikoon wuxuu ka kooban yahay tiro badan oo ah gobollo crystalline ah oo cabbirro kala duwan leh (dushu waa crystalline).
Kooxda hadhuudhka ah ee ku jihaysan way fududahay inay farageliyaan beddelka koronto-dhaliyaha ee isku-xidhka hadhuudhka, markaa waxtarka beddelka ee polysilicon waa mid hooseeya.Isla mar ahaantaana, joogteynta sifooyinka indhaha, korantada iyo farsamada ee polysilicon ma aha mid aad u fiican sida unugyada qorraxda ee monocrystalline silicon.Waxtarka ugu sarreeya ee shaybaarka unugyada cadceedda polycrystalline silikoon waa %, kan la ganacsadona guud ahaan waa 10% -16%.Unugga cadceedda ee polycrystalline silicon waa qayb labajibbaaran, kaas oo leh heerka buuxinta ugu sarreeya marka la samaynayo modules-ka qoraxda, alaabaduna aad ayey u qurux badan yihiin.Dhumucda unugyada cadceedda polycrystalline silikoon guud ahaan waa 220uM-300uM dhumucdiisuna waxay tahay 220uM-300uM, iyo qaar ka mid ah soosaarayaasha ayaa soo saaray unugyo qoraxda leh dhumucdiisuna tahay 180uM, waxayna u kobcayaan xagga khafiifinta si ay u badbaadiyaan agabka siliconka qaaliga ah.Waferrada polycrystalline waa labajibbaaran xagal-midig ah ama leydi ah, iyo afarta gees ee maroodiyaasha hal mar waxay ku wareegsan yihiin goobada.
Midka godka lacagta u samaysan ee dhexda ugu yaal waa hal crystal, kaas oo la arki karo marka la eego
